Supernumerary teeth formation following subluxation of primary incisors

Abstract

Supernumerary teeth are reported to occur in both primary and permanent dentitions, but their exact aetiology remains unclear. To date, there have been no documented reports of supernumerary teeth formation subsequent to traumatic dental injuries (TDIs) to the primary incisors. This case report illustrates such an unusual consequence where a supernumerary tooth developed subsequent to a subluxation injury to teeth 51 and 61 in a 4‐year‐old Caucasian girl. This emphasizes the importance of reviewing TDIs, as well as providing parents with sufficient information about possible sequelae at the time of trauma. Nevertheless, it also provides an excellent basis for future investigations, which are essential to establish this correlation and to prove causation.

Critical analysis of the reporting quality of case reports focusing on dental traumatology using the Preferred Reporting Items for Case reports in Endodontics 2020 checklist: A baseline evaluation prior to checklist publication

“…The characteristics of the 50 14–63 included case reports are presented in Table 1. The majority of the corresponding authors were from Brazil ( n = 11) and India ( n = 11).…”

Surgical Management of Impacted Supernumerary Tooth: A Case Series

“…In the first case, the parent has given a history of trauma in the primary dentition. 10 So, the etiology of trauma may be correlated with the development and the fusion of the supernumerary tooth. Another finding noted in the case was a perpendicular fusion of the supernumerary tooth with a permanent central incisor.…”

Dente supranumerário em região de mandíbula: relato de caso

“…O diagnóstico de hiperdontia muitas vezes ocorre incidentalmente, através de exames de rotina, como radiografias panorâmicas. Embora esse exame seja valioso para visualizar a relação dos dentes com estruturas vizinhas, ele é complementar ao exame clínico, sendo fundamental para identificar anomalias não perceptíveis apenas clinicamente (5,6). Quanto à morfologia, os dentes supranumerários podem ser classificados como conoides, tuberculados, suplementares e odontomas.…”

“…Dentes mesiodens, um tipo comum de hiperdontia, surgem entre os incisivos superiores e são frequentemente identificados durante a infância ou adolescência. Além disso, supranumerários na região de prémolares, paramolares (quando localizados lingual ou vestibularmente aos molares), distomolares (após os terceiros molares), e, em casos menos frequentes, no seio maxilar e cavidade nasal, adicionam complexidade à classificação e diagnóstico (5,9).…”
